SkiCat, it sounds like what everyone is getting at is that it can come down a little bit to what you like best, for the way you use your boat etc. Or maybe you just like the "feel" of one over the other and that's not the same for everyone.
Although, I'm definitely feeling a nod towards the modern 3 blades for your use. It sounds like the 4 blades give a little bit of stern lift and low end bite, which comes into play for stern heavy V-Drives and any boat running a lot of ballast. I know Reid and others have been known to let people try (test drive) props on their own boats. Your best bet might be to find someone willing to let you try-before-you-buy a couple of the props you're interested in. |

I think that tim's assessment of not a mind blowing change between the 4 and a new 3 would hold with the 1:1 props as well Brian. Steve Watkins tried and didnt buy a 540 over his 4 blade at Reid's in the fall. There is a difference, I could tell Steve's boat didnt have a 540 on it driving it in an irreverant and generally unsafe manner.. but would the average family boater more interested in watersports than beating up his boat notice $350 worth of difference.. no.
Skicat you dont have an 80 SN and you are not running silly ballast, if you have $350 to spend on your boat you want an acme 540 it is all around the best performing prop for your boat, and a big change over the stock federal or an oj legend. That is the first hand experience of someone who had the same hull and pays very close attention to performance.. take it or leave it. |

If as Jody alluded to earlier that the oj 3 blade xmp line is now more complete in terms of RH offerings then the 540's dominance may in fact be in question once again.. but one wasnt able to get an 13x12x1 RH OJ back when I was trying them out.

I think if you still had a cast prop and were shopping for a new one, that a 540 would probably outperform the 208 if you were looking to eek out the best holeshot and top end that you could. I wouldnt expect to see or feel a huge difference though- so since you already have the 208, the 540 probably isnt worth the expense. That being said, I would pose the question before the next reunion you attend and see if someone can bring a 540 for you to try. |

Lee, it is you who is not listening. Define performance. Are you talking holeshot? Top end? Fuel economy? Smoothness? Wake shape? Wake firmness? We have all been saying the same thing for 2 years now- it might be time to try a prop instead of asking the same question over and over! |

It's you who's not listening, performance will depend on HOW AND WHAT you use your boat for. IT DOES matter if your going for a cruise, taking a few buddies or pulling tubes, skiers or boarders. Any of the 3 props already mentioned, 540, 542 and 208 will outperform the stock prop in your boat. Now depending on the conditions you use your boat one would suit better than the other. I have already stated that I think the 540 is the best choice for you as it seems you want a "general use" prop. |

If you're not happy with it, send it back and try another one (542). I think most places are willing to let you do this.

Yes sir, it's a 3 blade. The 542 is also a 3 blade. The 208 is a 4. |

Skicat..Yes the 540 is a 3 bladed prop... I purchased one after Delta props offered us the deals on Acme props. I was running the original Federal prop on my 88. I swapped it out on Sunday and I noticed a signifgant difference and was very pleased with it. I use mine for both boarding and skiing which is why I went with the 540 instead of the 542.
To add to what Joe said... Swatkinz pulled of his 4 blade OJ and put on a 540 to see if there was an improvement. I went with him as I drove his boat (an 88) the day before and both our opinions were the same. The 540 did not perform as good as the 4 blade and WASN'T worth spending the money to replace it. That being said my honest opinion is that it is well worth the money to upgrade from the original federal 13x13. I am curious how the wake will be this spring when I weigh her down for boarding but am happy with what I saw from a drivers point of view at various speeds. Here is the thread I posted my results.

Luciano, I believe the 208 is probably better than the 542 or the 540 for the reasons you mentioned. |

Skicat, It seems like the purpose of the thread might be dead since you indicated that you were ordering the 540. I'm sure you'll be happy with the prop, however, I'll add to this thread to tell you my (average CC owner) experience with props. What you need to keep in mind is that JoeinNY, TRBENJ, Hollywood and many others on this site have tested these props ad nauseum on our hull both with stock motors and highly tuned engines. At Reid's last fall, I asked these guys to drive my boat, give it a workout and then provide an honest opinion on it's performance, specifically with reference to the prop. Keep in mind that I'm running a 4 blade OJ prop and not the original Federal. All three commented that they felt that the 540 would improve all around performance. While I don't doubt that hard data might show an improvement over my 4 blade and I do highly respect the above mentioned members' opinions, I tried it and there just wasn't enough of a difference to me to justify the price, but again I'm not as in tune with the feel drive, performance as these guys. Not many people are. However, I could tell immediately when Reid tapped the 2nd keg....had a slightly less bitter bouquet. Seriously, I think there'd be a big difference and that cost would be justified vs. the original Federal prop. That same weekend, I drove Morfoot's 88 with the old, original prop and there was a noticeable differnce b/w his prop and my 4 blade, but then again he's real hard on his equipment (beaches the boat, spills kool aid on the upholstery, runs 87 octane, uses Fram filters etc.)................................Kidding, Kidding! He's meticulous as his boat shows To sum it up, it didn't seem like you were hardcore enough in any one discipline, skiing, barefooting, cruising to really identify a single prop as being "the best". I'll bet you'll enjoy the performance of the 540, but would also be happy with a 4 blade like mine. Just keep in mind that these guys really, really look deep into this stuff. Don't get too bogged down in finding "the one do it all prop." It seems that all of these modern props should give better performance than the original, even for the average non-gear head CC owner. Good Luck! |

I'd expect the 4 blade to pull a smoother wake but the 208 is 12.5'' pitch, and if I'm getting 2450rpms at 21mph with the 11.5'' I'd expect, as you said yours perform, 2100-2200rpms at 21mph with the 208. That would surely not solve the throttle response. I think 2600-2700 rpms at boarding speeds will work best. What I'm not sure is if I could custom order an uncupped 4 blade 11.5'' or go with a cupped 11''. I will email Acme as my dad will visit the states on april. |

I guess I am not seeing what the throttle response issue for you is.
Even at 240 hp, the 208 even in my boat with a heavier floor setup than stock, and a fat sac and people in the boat, I never had issues with any range of power. The boat has always pulled extremely well with the 208, overloaded or not. I ran my boat from 02-08 with stock 240 hp and the 208. These motors are tuned to have a nice wide tq curve. I doubt there is much difference in tq from 2100-2700 rpm. All I can see by running 2600-2700 rpm is great fuel usage for boarding speed. |

Hokrn, look for Alan's post on torque curves, you'll see that above 2500 and up to 3500 is were these engines make real power (stock form). That's why I always suggest people using their boats for heavy load wakeboarding that they should try to prop their boats so that it falls in the 2700-3000rpm range at pulling speed.
It's easier with reduction gear boats, in fact V-drives come propped this way stock because they are heavy wakeboard specific boats. On 1:1 boats you compromise WOT speed and need to watch not to over-rev the engine. Have you ever seen a crank or bearings from a wakeboard engine pulling at 2000rpms? cylinder heads? valves? These boats were also meant to pull skiers at 3000rpms in their time. Fuel consumption even improves at pulling speed. If you ever get a heavy weight load on your boat, let's say 1400lbs, drive the boat and tell were the engine smoothens and pulls better, it will be at +2600rpms were it makes torque. Again, these are my thoughts and experience, and they are meant only for seriously weighted wakeboarding boats. |

If the MW Federal performance level is a 1, I'll give the OJ Legend a 7 with 8,9,10 going to the various ACME offerings depending on how you use your boat.
